  the 
  end 
  ; 
  it 
  is 
  densely 
  tomentose 
  like 
  the 
  back 
  

   of 
  the 
  mesonotum 
  (in 
  guimari 
  it 
  is 
  less 
  tomentose, 
  the 
  black 
  ground-colour 
  being 
  

   visible) 
  and 
  clothed 
  with 
  rather 
  long 
  pale

  which 
  are 
  blackened 
  on 
  the 
  apical 
  half 
  ; 
  3rd 
  and 
  4th 
  

   veins 
  straight 
  and 
  a 
  little 
  divergent 
  at 
  the 
  end, 
  while 
  the 
  2nd 
  is 
  more 
  strongly 
  

   divergent 
  from 
  the 
  3rd 
  ; 
  cross- 
  veins 
  straight 
  and 
  parallel, 
  the 
  small 
  one 
  placed 
  

   near 
  the 
  last 
  fourth 
  of 
  the 
  discoidal 
  cell, 
  the 
  posterior 
  one 
  longer 
  than 
  its 
  distance 
  

   from 
  the 
  small 
  one 
  ; 
  lower 
  corner 
  of 
  the 
  anal 
  cell 
  forming 
  a 
  wide 
  angle 
  ; 
  6th 
  vein 
  

   prolonged 
  to 
  the 
  hind 
  border, 
  even 
  if 
  very 
  faint. 
  The 
  stigma 
  is 
  very 
  short 
  and 
  

   pale 
  yellowish, 
  with 
  a 
  small 
  black 
  dot 
  near 
  the 
  base 
  of 
  the 
  costal 
  bristle 
  ; 
  the 
  first 
  

   vein 
  ends 
  much 
  before 
  the 
  small 
  cross-vein 
  (in 
  guimari 
  it 
  ends 
  below 
  or 
  only 
  a 
  

   little 
  before 
  it). 
  The 
  basal 
  half 
  of 
  the 
  wing 
  is 
  entirely 
  whitish 
  hyaline 
  and 
  quite 
  

   unspotted. 
  The 
  apical 
  part 
  is 
  occupied 
  by 
  a 
  dark 
  brown 
  patch, 
  which 
  is 
  less 
  dark 
  

   towards 
  the 
  hind 
  border, 
  and 
  has 
  a 
  yellowish 
  patch 
  on 
  the 
  small 
  cross- 
  vein 
  into 
  

   the 
  end 
  of 
  the 
  first 
  basal 
  cell, 
  prolonged 
  above 
  into 
  the 
  submarginal 
  cell 
  towards 
  

   the 
  stigma. 
  In 
  the 
  brown 
  patch 
  there 
  are 
  the 
  following 
  hyaline 
  spots 
  ; 
  two 
  spots 
  

   close 
  together 
  in 
  the 
  marginal 
  cell 
  just 
  beyond 
  the 
  stigma, 
  the 
  first 
  very 
  broad
